Police in Ohio say they have charged a woman with murder after she confessed to killing her three young sons over the past 13 months.

Police in Bellefontaine, about 60 miles northwest of Columbus, say 23-year-old Brittany Pilkington was charged with three counts of murder and jailed Tuesday. No attorney information was available for her.

She's accused in Tuesday's death of 3-month-old Noah Pilkington, as well that as Gavin Pilkington, who was 4 when he died on April 6, and Niall Pilkington, who was 3 months old when he died on July 22, 2014.

Officers went to the family's apartment on Tuesday morning after a 911 call that Noah wasn't breathing.

Authorities already were investigating the deaths of Niall and Gavin, whose causes of death haven't been determined.
